Bug Tracker

Affected Product:  See more info
F5OS Install/Upgrade, Velos(all modules)

Fixed In:
1.2.0

Opened: May 07, 2021
Severity: 2-Critical

Symptoms

Under certain Controller installation/upgrade conditions, a live upgrade of Controller Platform Services produces transient instability in running container versions after rebooting the affected Controller. This instability is fixed automatically within several minutes of controller reboot, but can have negative side effects.

Impact

The Controller will temporarily run the wrong version of platform containers after rebooting (it will run the container versions defined in the 'patch' version of services plus the container versions defined in the 'non-patch' version). If the patch version of services includes changes to the ConfD container, this can result in ConfD database corruption/instability.

Conditions

1. A Controller was imaged using a 'patch version' ISO (Ex. 1.1.1, 1.1.2). 2. The Controller Platform Services are live up/downgraded to a 'non-patch' version of controller services (Ex. 1.0.0, 1.1.0, 1.2.0). 3. The Controller is subsequently rebooted, either automatically or by the user.

Workaround

None

Fix Information

Fixed issue with Controller live upgrade instability affecting systems that were initially imaged with particular versions of Controller SW.
